Rare variant collection and easter skylanders

This is a message for portal masters, how do you get rare skylanders from way back from spyro's adventure like boomer because he's good, legendary variants, (I have legendary zoo lou and Free ranger but I need to know which one will be worth the trip), and is it still possible to get easter skylanders, I have been searching for tem and the internet lies to people. So help me! And tell me your havorite variant will ya?
